Dr. Daniel and his Cenegenics® team helped me to identify inflammation markers (CRP) in my body after shoulder surgery...I became allergic to plastic anchor inserted into my bone. I am maintaining this allergy w/o any of the side effects because of Dr Daniel’s suggestions and supplements. Cenegenics® helps me identify problems and find solutions to them in my performance training regimens!

I am 58 years old and thought I couldn't lose weight or look lean any more, but I was wrong. Dr. Daniel at Cenegenics® evaluated my current lifestyle, diet, exercise, and medical baseline. From that, we put things into action. Over the past year, I have lost 21 pounds of fat and gained 14 pounds of muscle going from a 30% total body fat to 17%. I went from a 36 to 30 inch waist line and have a ton more energy and feel great. This was accomplished with diet, nutrition and added workouts that targeted my goals. I went through a total medical evaluation that was the most inclusive test I have ever had. My sleep has improved and I no longer take medications for high blood pressure.
This is a way of life for me and I live every day to the fullest!!

I never imagined that at 46, I’d be in the best shape of my life! I was in need of a lifestyle change and luckily found the right place for guidance and help. Three years ago I was 232 lbs and 30 % body fat. I want to thank everyone at Cenegenics® for helping me reach goals that I wouldn’t have imagined possible! I’m now 220lbs. And a mere 12% body fat! That’s an amazing amount of lean tissue added and I couldn’t feel better. I’ve definitely put in the work but it would not have been possible without Cenegenics®!

The Cenegenics® program has changed my life. Even in my collegiate football playing days I was not in the shape that I am in now. Education, accountability, and teamwork have been the core principles I value in this program. I would forfeit any other monthly expense I have to remain a member of the Cenegenics® program because it has made that much of a difference for me.

The balanced supplements and nutrition advise from Cenegenics® has greatly helped with energy and joint pain so that I feel like exercising and have come to enjoy it again. Prior to Cenegenics® every time I tried to exercise my knees, shoulders, ankles, and elbow would hurt making me stop. Now with the balanced supplements I feel strong and feel the results of exercise in my muscles, which feels great, not in my joints.
Thank you for getting me back to where I love to exercise again and I enjoy the results.

I am stronger than ever before

I had a follow-up electrocardiogram last week. My cardiac ejection fraction before Cenegenics® Medical Institute therapies was 30%. Now after three months on my Cenegenics® program, it is now 55%, and my cardiac study was normal. The electro-physiologist told me “to keep doing what ever you are doing.” I intend to do that. I am stronger than ever before and keeping up with my seven-year-old daughter and twelve year-old son.

You have set a new standard of care

I appreciate the high level of care and service that I have received and continue to receive from you since I started the Cenegenics® program. You have always made yourself accessible and have responded immediately to any problems or questions I have had. You have set a new standard of care that I have not seen from any of my local doctors. Thanks again to you and your staff for all the support!

I am beyond impressed

I cannot believe after one month on the program how great I feel… [which was] further confirmed by my local physician who could not believe the weight loss and my general mood. She noted that I had lost 12 pounds and advised me to totally drop [the medication for] mild depression I had been taking for three years. I am beyond impressed at my libido, my energy and my enthusiasm for each day. Thank you, Cenegenics®, for showing me the way!

Ran one complete mile yesterday

I have successfully completed my first two weeks of my new diet/lifestyle… I feel better too–less bloated, lighter feeling, more energy—my afternoon siestas are no longer required. You have no idea how helpful you were in passing along the literature on diabetic—specific recipes and general information. Thank you. I have also attached my first week’s results from my exercise program . . .I actually ran one complete mile yesterday—that has not happened in a LONG time; it felt good to move/glide through space again. It is very exciting to be feeling better and stronger.

You have helped refocus my life

Not to be silly, but from the day I came to see you my life has dramatically changed. I was very unhappy with myself… Yesterday, I received a note from a lady in our church choir, wanting to know what I have done, and asking if I would talk with her son about diet and fitness. For some time, I have thought about retiring (again). As an interim step, I have accepted the presidency of Ronald McDonald Charities. Because of the new Vanderbilt Children’s Hospital, we are going to have to raise $7 -$10 million… I only share this with you so that you know how important and far-reaching your practice has become. You have helped refocus my life and I appreciate it. Often, we don’t know how many lives we have impacted.

... personally apprise you of the very positive experience I had

I am a new patient of your clinic. I visited your Las Vegas facility… for the initial evaluation. I was quite impressed with everyone that I came in contact with that day… I completed your evaluation form while I was there, but I wanted to “go the extra mile” and personally apprise you of the very positive experience I had. As the president of a service company (tax-free money management) as well, I am aware of how difficult it can be to have a staff that is professional, friendly, knowledgeable and well-trained at the same time. I had participated in another clinic’s program and the difference as the cliché states was night and day. I thought you would like to know.

I wake up in the morning feeling refreshed and in a good mood

My energy levels have increased dramatically. My moods are more consistent; I think clear and am much more focused. I am sleeping better and wake up in the morning feeling refreshed and in a good mood. I just finished a huge project that was very demanding and never ran short of energy or felt that I could not handle the workload.

The most comprehensive evaluation of my health status

It was the most comprehensive evaluation of my health status that I’ve ever experienced.

I haven’t been this lean in 20 years and it feels great

My body composition has changed dramatically. I haven’t been this lean in 20 years and it feels great! My wife is very happy as well…wink wink. My friends and co-workers have all commented on how vital and bright I appear in contrast to the tired and haggard ‘me’ they had grown accustomed to.



Ran one complete mile yesterday

I am truly amazed at the sincere approach you have in helping me make some tough life decisions and changes. When I was at your facility, I felt a strong sense of caring from you and all your staff that I have never felt from any other medical facility since my angioplasty, two years ago. Everything about Cenegenics® is so amazingly refreshing and different from the normal apathetic approach to medicine. I had almost lost my faith in the medical practice before I happened to see your ad in the newspaper… I was surprised at the speedy response I received… [a Cenegenics® physician] and I talked for quite a long while, which never happens anywhere else. Your assistants were marvelous . . . friendly and sincere. They did a great job helping me feel comfortable in my room and serving an excellent tasty light lunch. My nutritionist helped map out the direction that I will be going and made sure I understood why these changes were necessary. She truly knows her stuff and has a great way about her delivery… In this world, where people have become so disconnected from each other and no one or nothing truly has any value. I have come to a deep understanding that quality people should be recognized. You and your staff are the best in the business and certainly worth every penny.

The staff was helpful and kind

I would like to thank you for such a wonderful time with you and your staff. I [am] looking forward to all the great results. This morning I have starting talking with my parents about your services and will continue to do so. I feel they can both benefit greatly for it… [The Cenegenics® physician] was very nice and took the time to hear what I had to say and also gave me some important information. The staff was helpful and kind. I look forward to working with you… and your staff. Mahalo, that means, “thank you.”

Being healthy enough

I am back full time on Real Estate transactions. I thank you and your team for that. Being healthy enough to do real estate full time is a big deal to me.

I am amazed at my new-found strength

Walking into Dr. Barber’s office a year and a half ago, I was a pale shadow of who I am today. I was exhausted, depressed, overweight and weak. I was so tired that I spent days in bed with little energy – only able to get a few necessary chores done each day. Needless to say I was unhappy and pretty much unproductive. Not a good way to be living at only 56 years old. Today, I can say I’m a happy, vital person enjoying a fruitful, active life. I work out at Gold’s Gym with a trainer three days a week. I am amazed at my new-found strength and love my toned, shapely body. My skin looks gorgeous, and I sleep well each night. I now have the energy to work many hours a week in dog rescue with plenty of zest left over for fun. The best part has been my sex life – I feel like I’m 17 again! Overall, I look and feel great; better than I have for many years. Carefully following the program prescribed by Dr. Barber, I changed my eating habits, slowly ramped up my exercise over time and religiously took the recommended vitamins and supplements. With monthly blood work and calls with Dr. Barber, we gradually figured out what worked best for my body. The changes didn’t happen overnight, and Dr. Barber was patient, responsive and supportive until we got it right. The program is well-run and the staff is friendly, talented and great to deal with. Emails and issues are handled expeditiously, with a smile. It might be too much to say that Cenegenics® and Dr. Barber saved my life, but it feels that way. I now look forward to fully-enjoying what life holds for me.
